This is a new catalog listing Ivanhoe Metal Reflectors and Fittings for 
Industrial [}]umination. The Ivanhoe line has been revised, some numbers 
being discontinued, while new developments and designs have been added. 


Holders Nos. 608 and 609 are new products. They fit B-heel reflectors 
which are provided with two lugs, as illustrated herein. 


Until January 1, 1924, all B-heel reflectors for use with the No. 608 and 
No. 609 holders must be specified as BEDD-100 with lugs, BEB-200 with 


lugs, BEL-75 with lugs, etc. They must be ordered with the holders to avoid 
confusion. 


Unless B-heel reflectors with lugs are specified on an order, the reflector 
without lugs will be supplied until present stocks are exhausted, after which 
time all B-heel reflectors will become standard with lugs. 


The lugs will not interfere with the use of the other Ivanhoe 214” and 
314” holders listed in this catalog. :

SERVICE TO LAMPS 


Mazda lamps are the most convenient and eco-

good volume of light, the light radiates from the 
lamps in all directions, and a great deal of it is

In other words, light from bare Mazda lamps is

raw material. 

To utilize this raw material most effectively is 
the idea incorporated in the Ivanhoe slogan of 
Service to Lamps. Light, to be useful, must be 
transformed into illumination. The light must be 
directed where it is needed, and its quality improved 
by diffusion so that glare is reduced and shadows 
softened. These results are brought about by the 
use of scientifically designed reflectors, installed in 
accordance with approved engineering practice. 

The need for good artificial illumination is evi- 
dent when it is considered that near the middle of 
the day a work-bench near a window may have an 
intensity of ten or fifteen foot candles of daylight. 
The light will be well diffused, casting shadows that 
are soft and luminous, so that the workman can 
perform his duties with ease and comfort. It is 
obvious that when darkness comes on the work 
must suffer if it is performed under light of one or 
two foot-candles, and improperly reflected so that 
glare and sharp shadows are present. 

It has been found by careful tests that Productive 
Intensities have increased production from 6 to 
33% over that in poorly lighted rooms or work 
shops. 

Productive Intensities approximate very closely, 


both in quality and quantity, average daylight 
illumination received upon the work. 

The tests were all conducted in metal working 
shops where the class of work ranged from rough 
machining and assembling to accurate tool work. 
Records of production with an inadequate lighting 
system were kept and then with a properly designed 
system where the latest types of Mazda lamps and 
Industrial Reflectors were used. 

Plants are operating today where an improve- 
ment in the lighting would mean a like increase in 
production. 

In order that illumination intensities may be 
measured conveniently, the Foot-Candle Meter was 
perfected. This instrument is shown below. As 
the name implies, it is an instrument for measuring 
illumination intensities in foot-candles, the unit 
The foot-candle is the unit of 
measurement of illumination intensity, as the 
degree Fahrenheit is the unit of measurement of 
temperature, or pounds per square inch the unit of 


of measurement. 


measurement of pressure. 

There is no longer any reason for doubt or un- 
certainty regarding a lighting system. Ivanhoe 
representatives are at your service with a Foot- 
Candle Meter and practical engineering knowledge 
of illuminating requirements. 

There is an Ivanhoe reflector for every service, 
to make good the Ivanhoe slogan of Service to 


Lamps. But the final Ivanhoe ideal is Service to 
Industry—a service which improves working con- 





ditions so as to increase production, reduce spoilage, 
and raise the standard of quality of the goods 
manufactured.

HOW TO PLAN A LIGHTING SYSTEM 
CLASSES OF LIGHTING 


It is the object of this section to give general 
engineering data which will assist in providing 
better illumination most economically, without 
entering into a discussion of fundamental principles. 

The first consideration in making a light installa- 
tion should be to decide what kind of lighting is 
best adapted to the particular industry involved. 

All industrial lighting may be divided into three 
classes: General Overhead lighting, Group Light- 
ing, and Local Lighting. 


General Overhead Lighting 


With General Overhead Lighting, the room is 
lighted as a whole without reference to the work done 
at any particular point. With this system the light 
should be sufficient for the character of work per- 
formed at every point in the room. The distrib_ 
uted unit system is employed, in which lights are 
arranged in imaginary squares, or 
nearly square. 


rectangles 


Where coarse work is performed the squares may 
be large; where fine work is performed they should 
be small. A size of square and mounting-height 
which call for the use of the standard Bowl or Dome 
reflector (see page 8) is usually the best. 

For coarse work, however, and for such places as 


warehouses, distributing type reflectors are desir- 
able, with the spacing between outlets from two 
to two and one-half times the mounting-height. 


Group Lighting 


Group Lighting, or, as it is often called, Localized 
General Lighting, consists in lighting a particular 
group of machines, or a particular area by Overhead 
Lighting. It is sometimes difficult to distinguish 
between General Overhead Lighting and Group 
Lighting, but in the former the room itself is lighted 
without reference to the location of the work, while in 
the latter the lights are always placed with particular 
reference to the location of the work, 


Local Lighting 


Local Lighting is the lighting of any individual 
machine or operation, usually with a single lamp 
and reflector. It is ordinarily employed to supple- 
ment General Overhead Lighting of low inten- 
sity. Local Lighting is used on work-benches, lathes, 
sewing-machines, punch-presses, drawing-presses, 
or for any kind of work where a light may be needed 
from a nearly horizontal direction, or where a high 
intensity of illumination is

WHERE AND HOW TO USE DIFFERENT TYPES 
OF REFLECTORS 


In order to meet all the requirements of industrial 
plants, the Ivanhoe line offers several types of stand- 
ard reflectors for each class of lighting. These 
may be grouped as they apply to the three general 
classifications already outlined, namely: General 
Overhead, Group and Local. 

Illumination requirements for General Overhead 
and Group Lighting being such that the same re- 
flectors are usually applicable to both classes of 
service, the following general classification may be 
made. 


The RLM Standard Dome 


These reflectors are gen- 
erally applicable to any 
industries which may be 
classified as Rough Manu- 
facturing, Medium Manu- 
facturing, or Fine Manu- 
facturing. With them a 
great deal of light is di- 
rected at the higher angles, and they are, therefore, 
especially suitable for operations where the work is 
performed on vertical surfaces. The depth of the 
RL M standard dome is such that ample protection 
from the glare of the lamp filament is provided when 
the reflector is used on the average mounting-height. 
However, best practice requires that bowl-enameled 
lamps be used in order to conceal the lamp filament. 

When these reflectors are used it will usually be in 
accordance with the rules for General Overhead 
Lighting. The distance apart should be approxi-

mately one and two-thirds times the mounting- 
height above the work. This ratio can be increased 
to two or two and one-half where uniform illumina- 
tion is not required, as in warehouses and spaces 
where rough work is performed. 


The Glassteel Diffuser 
The Glassteel Dif- 


fuser, designed for high 
wattage Mazda C 
lamps, is a combina- 
, tion consisting of an 
extra large dome reflec- 
tor and an enclosing 
globe of light-density 
diffusing glass that en- 
tirely surrounds the lamp. The large reflector and 
diffusing globe greatly reduce brightness and afford 
excellent diffusion. The top of the reflector is per- 
forated, through which lght passes 
upward so that the entire work- 
room may be lighted. The enclosing 
globe permits the use of the high watt- 
age lamps necessary for high intensities 
with a minimum of glare. All these 
features combine to closely simulate 
the intensities, diffusion, soft shadows, 
general lighting and ideal qualities so 
desirable in daylight illumination. 

The reflector is white porcelain 
enameled inside and outside and with 
the white opal globe is inconspicuous 
even though it is large in size. The 
finish of the reflector and smooth sur- 
face of the glass make cleaning easy. 

It is designed for use in those in- 
dustries where the highest type of 
illumination is desired; where high 
intensities are essential; where direct 
or reflected glare must be eliminated; 
where diffusion of light is required for 
distribution and to prevent dense 
shadows, and where work on vertical 
surfaces predominates. 







AN 
SERVICE! To LAMPS 





One very distinct advantage for 
this unit is the fact that Mazda C 
Daylight lamps may be used with but 
very little change in color of the light 
as produced by these lamps. For 
utmost efficiency these lamps should 
be used clear and the Glassteel Dif- 
fuser at once provides an_ efficient 
accessory eliminating the brightness 
of the clear bulb lamps. 

It should be spaced not more than 
114 times the mounting-height above 
the work for uniform illumination. 


The Standard Bowl Reflector 





Rules for the in- 
stallation of the 
bowl type reflector 
are very closely re- 
lated to those given 
for the Dome Type 

: in a preceding par- 
agraph, but with this type the lamp 
filament is shielded at a lower angle, 
and they are sometimes preferable

Figure 3. 


to Dome reflectors for General 
Overhead Lighting. For the same 


reason they are especially suitable for installations 
where reflectors must be mounted low, in order 
that operators will not be annoyed by excessive glare. 
The distribution of light is rather strongly downward, 
and for this reason they are preferable for installations 
where reflectors must be mounted at a considerable 
height to clear cranes, or to conform to the construc- 
tion of the building. Bowl reflectors are also suitable, 
in the smaller sizes, for Local Lighting where a high 
intensity is desired over a small area. 

Bowl reflectors should be spaced a distance apart 
approximately one and two-thirds times the mount- 
ing-height above the work for either General Over- 
head or Group Lighting, and when used for Local 
Lighting, must, of course, be located with reference 
to the work. 


Glass-Top Reflectors 


This type is a develop- 
ment for use in factories 
where the general appear- 
ance of the workroom is 
considered essential to good 
workmanship and content- 
ment of employees. 

The popular Dome Type is available in this new 
design. This standard form is used, with a small 
portion of the top cut away. The opening is covered 
with a light density, diffusing glass cover permitting 
a small amount of light (from 8 to 10%) to pass 
upward, in order that the ceiling and top walls may 
be illuminated to a desirable brightness. 

This feature relieves the contrast in brightness 
between the area below and above the lighting units, 
and can be noted by comparing Figs. 2 and 3. The

Note the Illumination of the Equipment above the Level of the Reflectors. 


light above the unit also serves to illuminate the 
pulleys, line shafting and other machinery above 
the level of the reflectors so that repairs can be made 
conveniently. 

The efficiency of these reflectors varies but a small 
percentage in the amount of light directed to the 
working area as compared with the standard RLM 
Dome Type reflectors, so that their application is 
the same as for those reflectors described in preceding 
paragraphs, 


Angle Type 


Angle type reflectors may 
be classified as special service 
reflectors. They are particu- 
larly desirable in the large 
sizes in such industries as 
erecting shops, machine shops 
where traveling cranes are 
used overhead, and — similar 
classes of work. In such 
installations the overhead 
lighting often comes from re- 
flectors mounted rather high, and it is usually 
necessary to build up the illumination on the work- 
ing plan from the side. In such cases Angle 
Reflectors are mounted along the side walls below 
the crane rails, at a suitable mounting-height, the 
distribution being such that the light is directed 
away from the wall, and toward the center of the 
room. Both the horizontal and vertical illumina- 
tion is built up, and light is received upon the work 
from each side, as well as directly overhead. This is 
an advantage in softening shadows. In the smaller 
sizes this type is very good for Local Lighting, where

outlets must be located close to the work and it is 
desirable to screen the lamps from the operator. 

Angle reflectors are required for sign and_bill- 
board lighting, and are being used extensively for 
this class of service lighting. Special installation 
data is available for this class of service and may 
be had on request. 

Vapor-Proof Reflectors 

Vapor-proof fittings afford 
a safe means of providing illu- 
mination for such industries as 
powder plants, flour mills, oil 
. refineries and similar indus- 
® tries where it is essential that 
electrical connections and 
lamps. be protected from acid 
fumes or inflammable dust or vapors. In order 
that the light from these fittings may be efficiently 
utilized there are Ivanhoe reflectors made to fit 
the equipment available. 

The RLM Dome form has been adapted for use 
on these fittings, therefore the performance charac- 
teristics are very similar. ‘The angle of cut-off and 
distribution are about the same with slightly lower 
efficiency due to the large fitter and use of the globe 
and guard. They are porcelain-enamel finished 
inside and outside to stand up under the severe 
service conditions expected. 

They should be spaced one and two- 
thirds times their mounting-height 
above the work. 


Mazda C Enclosing Units 


With the advent of the larger sizes 
of Mazda C lamps, there came a demand 
for this type of completely enclosing 

7 units for display lighting, for store 
aP fronts, and similar outdoor lighting. 








A Good Example of Illumination of a Large Interior. 
Ivanhoe R L M Standard Dome or Bowl Type 


These units are of heavy construction, 
and will stand up satisfactorily under 
the varying conditions of the weather. 
The globes are excellent diffusers and 
their absorption is low. 

This type of unit is sometimes used 
indoors, for General Overhead Light- 
ing, and in such cases it is preferable 
to use the unit with the reflector in 
order to take advantage of the increase 
in downward light. 


Wide Type Reflectors 


The Flat Concentric 
Reflector should be 
used only for outdoor 
lighting, as in yards, 
and on platforms, where a wide distri- 
bution of light is required, and it is 
not important that the lamps be 
screened. Reflectors are furnished in 
the R style only, with a solid top of 
rigid construction, containing a porce- 
lain socket. The reflectors are weather- 
proof and easy to wire. 





Reflectors 


Shallow Dome Reflectors 


The Shallow Dome Type also 
produces a wide distribution of 
light, but is deeper, affording 
“much better protection from 
7 ee the brignt.tiaiienn. 

This type is suitable for indoor installations on 
wide spacing, in storage spaces, and similar locations 
where close vision is not required. This type is 
available in both paint-enamel and_ porcelain- 
enamel finishes. 





Reflectors for Mill Type Lamps 


Where the lamp must be located 
near the work and is subject to 
excessive vibration or abuse in hand- 
ling, the Mazda Mill Type is the 
most serviceable. There are several 
types of Ivanhoe reflectors available 
for these lamps, including the Bowl, Angle and Dome 
types. These reflectors are small in diameter and 
deep in order to conceal and protect the lamp. A 
special small reflector is made for use on power 
machines where it is located close to but must not 
conceal the work. 





Special Service Reflectors 


There are some requirements which 
can only be met with specially designed 
reflectors. Tennis Courts, Sewing Ma- 
chines, Mail Cases and other localized 
operations all require special equipment. 
Ivanhoe reflectors for Special Service have been 
designed to produce certain predetermined results 
best serving these individual requirements.

INTENSITY OF LIGHT REQUIRED FOR VARIOUS 
KINDS OF WORK 


For the effective and economical production of work, it is important that a sufficient intensity of light 
be provided. The following table shows the intensities in foot-candles required for various classes of 
manufacturing. These intensities apply under all average conditions and represent present standard light- 
ing practice, having been revised in accordance with the present practice of specifying Productive Intensities. 

A range of choice is provided by recommending limits of intensity, as ““3 to 6,” “5 to 10,” “8 to 16,” 


“10 and upward.”

LOCATION OF OUTLETS 


It is important in any class of lighting that outlets 
be properly located. This applies to all three 
classes of lighting previously described; namely, 
General Overhead Lighting, Group Lighting and 


~ 


Local Lighting. It is obvious that for Local or 
Group Lighting outlets should be located with 
reference to the work. For General Overhead 
Lighting, however, it is desirable to locate outlets 


STEEL (hil REFLECTORS 





symmetrically, employing the distributed unit 
system. For this system outlets are located at the 
centers of imaginary squares or rectangles nearly 
square. Ceiling heights and the sizes of bays are the 
important factors controlling the location of outlets 
for this system. 

The distribution characteristics of a_ reflector 
must also be considered. The maximum spacing 
or distance between outlets for a reflector when 
suspended a certain height above the work is de- 


termined from its distribution. Therefore, a 


definite factor expressing this relation can be 
determined. When this relation is_ followed, 
uniform illumination will result. The following 


table has been compiled, showing the maximum 
distances between outlets for different types of 
reflectors when reflectors are suspended at stated 
distances above the floor, considering the work on 
a plane 2 feet 6 inches above the floor. The 
spacing can be determined when the mounting- 
height is the controlling factor, or vice versa.

FINISHES ON IVANHOE REFLECTORS 


Ivanhoe reflectors are stamped or drawn of open-hearth steel and supplied in three standard finishes: 
porcelain enamel, aluminum, and paint enamel. 

It has been found that in most classes of manufacturing, the porcelain-enameled reflector is most serv- 
iceable, as this finish will stand up under dirt, moisture, and acid fumes with but little deterioration of the 
reflecting surface. These reflectors are also easy to clean, which is an important factor to consider. — Reflec- 
tors finished with paint enamel can be used successfully in light manufacturing operations, and in those 
industries where conditions are generally clean. 


Porcelain Enamel: 


This finish is applied to the inside of the reflectors in three coats. The first is a binding coat, and it is 
covered by two coats of white porcelain enamel. The outside of the reflectors is treated with the same 
binding coat, and covered with one application of dark green porcelain enamel. 


Paint Enamel: 


The inside of the reflector is covered with a binding coat, and two coats of glossy white paint enamel. 
A glossy green paint enamel is applied to the outer surface, and baked on to insure a tough and durable 
finish. The color is permanent.

FEATURES OF IVANHOE PACKING 


The packing of Ivanhoe Metal Reflectors is at once compact, light and 
secure. It eliminates the use of materials undesirable from the stand- 
points of cleanliness and economy of space and at the same time 
assures a degree of safety in shipping not 
attained by the use of more bulky 
systems of packing. 















Designed by experts in modern 
methods of packing, the packages used 
for shipping Ivanhoe Reflectors occupy 
little more volume than the Reflectors 
themselves and add but little to the 
actual weight of the goods, while pro- 
viding ample protection and affording 
clear identification of package contents, 
all advantages in shipping. The illus- 
trations show the design and label of 
a typical standard package of Ivanhoe 


Metal Reflectors.

DOME TYPE 


For Medium Base Sockets « 
For 75, 100, 150 and 200-watt Mazda C Lamps 


These reflectors are made only in the standard Dome Type. The contour of 
the Glass-Top Reflectors conforms to that of the RLM Standard Dome Reflectors. 
Glass-Top Reflectors are. porcelain-enameled, green outside and white inside. 
The metal part of the reflector is one compact piece, the form and the heel being 
connected by substantial legs rigidly welded. 

A glass section of good quality opal glass of light density and excellent diffusing 
properties permits a portion of the light to be transmitted above the hanging- 
height of the reflector. The glass section is firmly held in place by metal clips. 
The light transmitted by the glass section is not large in comparison with that 
in other directions, but it is sufficient to serve the definite purpose of relieving 
the contrast between the areas below and above the plane of the lighting units 
as well as lighting any equipment, as pulleys, belts and shafting mounted above 
the level of the reflectors. 

For uniform illumination, Glass-Top Reflectors should be spaced not to exceed 
one and two-thirds times their height above the work.
